I've got an idea and I'm wondering if it's been tried before. I've got a bass that I use for testing things out. I've never tested out preamps like this, but I do have a half-decent understanding of electronics. P's have 2 coils traditionally run in series, but sometimes parallel. P's often don't have preamps, but it would be interesting to see how that works out. BUt not just any preamp. I thought it would be interesting to build a preamp w/ 2 buffers, 1 for each pickup. This would isolate the two coils so the impedance/capacitance of one would not kill the overtones of the other. The two signals would then be mixed and potentially amplified because I am also considering underwound coils to really bring out the top end. Between the mixer and gain stages, I would put the tone controls I know a lot of people like the P for it's thump. I think this would retain the bottom end, but it would add some zing to the top. The tone controls can be used to dial it back down if I want a real low end. So, has anyone ever tried this? What do you think? BTW, the seed for this idea came when I ran across a cache of surplus good quality quad op amp chips and I thought "What can I do w 4 op amps in one circuit? Ah, buffers, mixer and gain!", so I won't be out anything except time for trying.
